Go to the wii option as this will take you to the system menu. Interestingly seems as though your bootmi must be boot2. You should really follow the guide before attampting anything else as this would have explained what to do.

Forget about syncing the wiimotes, i think you should know by now it isn't an option yet. Put the sd card in the pc and put the bootmi folder somewhere on the pc and off of the sd card. then reboot the wii.
